The score of the Master of Engineering at Jiaotong University is over. Let's celebrate it first. However, it is not a few days before the review. This is a professional course for the university. I will review a course every day.
Start with the computer composition principle.
Focus
- The history of computer development focuses on the structure (operation, control, storage, input/output) of the Von norm machine ).
- Hexadecimal conversion (generally using binary as the intermediary)
- Various codes (the most important one is the complement code)
- Various binary operations (mainly using the addition and subtraction of the complement code, pay attention to the overflow problem during the same number)
- Parity (check the number of values in 1. For example, odd values in 1 are equal to 0)
- CRC verification code
- Memory (RAM, ROM)
- Memory expansion (bit extension, word extension)
- Commands (addressing)
- Proteus
- Microprogram composition command
- Three-tier Storage System
- Memory Replacement Algorithm (FIFO, LRU)
- Segment-and-page storage (segments are prone to fragmentation and are not easy to manage)
- Secondary storage (magnetic recording)
- I/O system (mainly understanding interrupt and interrupt shielding)
